Screen Corners fixes rounded bottom corners of MacBook display

A free utility called Screen Corners has been developed for MacBooks with Apple M processors, addressing a minor macOS interface display quirk. Due to differences between the physical shape of the display corners and the system elements' rounding, triangular sections of wallpapers sometimes remain visible at the bottom of the screen.

The application was created using Claude and Swift. It adds two small black masks to the bottom corners of the built-in display, concealing these sections. These masks remain on top of windows, the Dock, and full-screen applications, work across all virtual desktops, and do not interfere with clicking on interface elements.

Via the menu bar icon, users can adjust the rounding radius, enable processing for the top corners and external monitors, and activate automatic launch. According to the developer, the utility places minimal strain on the CPU, as it uses four static windows that update only when display configurations change.

Screen Corners is distributed free of charge under the MIT license, does not use telemetry, and has no third-party dependencies. The application supports macOS 13 and later versions. Installation requires Xcode Command Line Tools: the program is built directly on the user's computer, avoiding the standard Gatekeeper warning for unsigned applications.
